What is the purpose of using a CSS style switcher based on server-side time in PHP?

Using a CSS style switcher based on server-side time in PHP allows you to automatically switch between different stylesheets depending on the time of day. This can be useful for creating a dynamic and visually appealing website that changes its appearance based on the time, such as switching to a dark theme at night and a light theme during the day. 

<?php
$hour = date('G');
$stylesheet = ($hour >= 6 && $hour < 18) ? 'day.css' : 'night.css';
?>

<link rel="stylesheet" type="text/css" href="<?php echo $stylesheet; ?>">
